Question

−3,59 x + 13 + 5,8 = (9 + 5,8) − 3,99x. х=?

Answer 1

Ответ:

=-3,59x+18,8=14,8-3,99x

-3,59x+3,99x= 14,8-18,8

0,4x=-4

X=-10

Answer 2

Let's solve the equation step by step:

−3.59x + 13 + 5.8 = (9 + 5.8) − 3.99x

Combine the constants on both sides:

−3.59x + 18.8 = 14.8 − 3.99x

To isolate the x terms, we can add 3.99x to both sides:

−3.59x + 3.99x + 18.8 = 14.8

Combine the x terms on the left side:

(3.99x - 3.59x) + 18.8 = 14.8

(3.99 - 3.59)x + 18.8 = 14.8

Simplify the coefficients:

0.4x + 18.8 = 14.8

To isolate the x term, we can subtract 18.8 from both sides:

0.4x + 18.8 - 18.8 = 14.8 - 18.8

0.4x = -4

Finally, to solve for x, we divide both sides by 0.4:

x = -4 / 0.4

x = -10

Therefore, the value of x is -10.
